Scaling Devices for Aruba Central (on-premises)

Aruba Central supports switches, controllers, Instant APs, and Campus APs Campus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on.. Aruba Central can be implemented on multiple nodes. Accordingly, the number of supported devices increase.
